BUTTON-SETTING MACHINE-l SPECIFICATION forming part of Letters Patent No. 608,933, dated August 9, 1898.

Application filed January 18, 1897. Serial No. 619,543. (No model.) l

T all whom it may concern..- Y

Be it known that I, SAMUEL UPTON, a citizen of the United States, residing at Somerville, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Button-Setting Machines, of which the following is a specification. v

My invention relates to that class of machines for mechanically riveting a button to a garment by means of a rivet or tack which is driven through the material and suitably headed or upset within the button; and it consists of certain novel features of "construction whereby by a single stroke of a treadle the motions are producedwhich are necessary to feed a tack to the dies and rivet it into the button, all. of which is hereinafter set forth, reference being had to the accompanying drawings, wherein- Figure 1 is a side view of my machine, shown p part in elevation and part in section. Fig` 2 is a lan of same. Fig. 3 is an enlarged section of receiving-head and connection on the line X X, Fig. 2. Fig. 4. is a vertical section showing connection of `turret withrhead of machine. f

In my machine, A is the head B the table, and C the stand. D is the treadle, which, as shown,V is a bell-crank lever pivoted at its angle d to the standard C. Therfront end of this treadle projects out within reach of the operators foot. It is held up by the spiral spring E, which, as shown, is attached at its upper end e to the standard and at its lower end e' to the treadle. The upperfend of the treadle is connected by means of the adjustable screw connecting-rod F with the double bell-crank lever G, which is pivoted at g to the ends of the two rearwardly and downwardly sloping arms A2, (only one being shown, which are a continuation of the plunger-casing A', all being integral with the head A. It will be seen that as the treadle D is moved by the foot the lever G is made to oscillate on its pivot g and actuate, by means of the front arm g2 and connecting-rod I, the plunger H. At the same time by means of the rear arm g3, connecting-rod J, which passes up through the table B, bell-crank j, pivoted to the head A, and connecting-rod 7c the oscillating piece K is operated. This in turn operates the pawl and ratchet L, which turns the reservoir M5 from which the tacks are fed to the delivery-chute N, and also by means of the rod O operates the gate o and causes it to oscillate in such a way across the chute that the tacks which have been fed from the reservoir are delivered one at each stroke of the treadle to the receiving-head at the foot of the chute,

where they fall upon the cu p-sleeved plunger H, as hereinafter described..

g4 is a fourth arm of the double bell-crank lever G, whose end strikes against the casting h', and thus acts as a stop to limit the upward motion of the treadle when the parts are all in their normal positions.

The plunger I-I, which moves in the casing A', is constructed as shown in the section Figs. land 3.

Set into the v top of the piston H', which forms the bearing-surface of the lower end of the plunger, is the rod P, held in place by the flange p and screwp'. Rod P carries on its upper end the sleeveQ, which can slide vertically on the rod P, butwhose motion is limited by the pin q,passin g through the rod P and vertical slot q in thesleeve Q. The sleeve is held normally in' its lupper position by the spiral spring R, bearing'on theanges p of the rod P and r on the lower end o f the sleeve Q. When in this normal lposition, the upper end of the sleeve Q, projects beyond the end of the rod P, thereby forming av little pocket or cup S within the receiving-headV T, into which the tack drops from the Vfoot of the chute N. The sleevelQ ofthe cup-sleeved plunger H slides in the receiving-head T, which is a bushing let into the upper end of the plunger-casing A and held in place by the 4screw t. The receiving-head T is shaped as shown, being cylindrical andhavin g the lower flange T' and upper flange T2, also on its side the lugaf', which formsa support for and continuation of the lower` end of thel chute N,"which communicates with the interiorof the receiving-head T through a lateral aperture `252 in its side. .I preferably provide the receiving-head with an internal steel quill U.

In the operation of the machine when the treadle and plunger are in their normal position a tack which has been allowed by the gate o to fall to the receiving-head T at the lower endof the chute will drop into the cup S on the top of the plunger. As the foot is pressed upon the treadle the plunger II is made to ascend, carrying with it the rod P and its cup-forming sleeve Q. The tack in the cup is thus forced up against the goods, which are placed on the flange T2 of the receiving-head T. Vhen the sleeve Q has advanced a suficient distance, it is arranged so that its flange r will strike against the lower end of the receiving-head T, thereby arresting its progress, while the rod P will be still forced upward through the sleeve compressing the spring R, and the tack, which rests upon its end, will be driven home into the button which has previously been placed upon and held by the die V. Thus the point of the tack is protected by the sleeve Q until it has entered the goods and button. Otherwise it would be brushed aside and fail to enter the button true.

By the arrangement of the treadle D and connecting -rod F a toggle -joint is formed which will straighten out as the treadle is depressed, thus producing great power at the end of the stroke, where it is most needed to drive the tack home.

My turret M is supported by the arm W,

secured to the side of the head A by the bolt ct, as shown in Fig. 4c.

A conical bossw on the end of the arm W, ttin g into a corresponding depression on the head, allows the arm to be swung around at any angle and clamped firmly by the bolt a. The turret is secured to the upper end of the arm W by a sleeve m', integral with the base M' of the turret, passing through a hub w 011 the end of the arm W, so that the turret can be swung at any angle. The receiving-head T can `also be swung around in a horizontal plane, so as to bring the axis of the lug 15/ in line with the axis of the delivery-chute.

These adjustable connections make it a very simple operation to set my machine up, and at the same time make the whole very rigid, as the chute N, which is bolted at its upper end to the turret-base and at its lower end n to the lug z5 of the receiving-head, holds the parts firmly together, the feeding mechanism being securedto the head Ain two places and with no binding of the parts.

I claiml. In a button-setting machine, the combination of a button-holding die, a deliverychute, a separator for feeding a single tack or rivet from the string of tacks inthe chute, a plunger with a sleeve at its upper end forming a cup for receiving the tack, a receivinghead above the plunger and a spring-treadle and connected mechanism for operating the plunger and distributing, separating and upsetting the tacks, substantially as described.

2. In a button-setting machine, the combination of a foot-treadle provided with a fourarm bell-crank lever, with a button-setting plunger, a feeding mechanism and a stop connected respectively with the arms of the said bell-crank lever, substantially as described.

3. In a button -setting machine, a fourarmed bell-crank lever, a treadle for operating the same, tack distributing, separating, and upsetting mechanism, and connectinglevers, in combination with button-holding mechanism, substantially as described.

4E. In a button-setting machine, a deliveryreservoir provided with a supporting-arm, pivoted at each end, and a delivery-chute and button-holding head, whereby7 the said reservoir is adjustably secured to the head at two points, substantially as described.

5. In a button-setting machine, a fourarmed bell-crank lever, one arm connected adj ustably with the treadle, one connected to the plunger, one connected by intermediate levers to the hopper and separator, and the fourth arm forming a brake, in combination with a plunger, button-holding head, and tack holding, feeding and delivering mechanism, substantially as described.

6. In abutton-setting machine, a receivinghead T having at its upper end a tack or rivet receiving aperture 152, and a lug t' forming a continuation of the chute, substantially as shown and described.

In witness whereof I have hereunto set my hand.

SAMUEL UITON.
